[CentOS] logwatch named logs

ever since implementing the no-recursion-on-outside queries fix on one 
of my name servers, my logwatch emails have been 10-20MB/day, filled 
with crud like...

     client 10.191.192.212 query (cache) 'm.777.liyuanxi.com/A/IN' denied: 1 Time(s)
     client 10.192.34.96 query (cache) 'dyjwntl.www.0411gogo.com/A/IN' denied: 1 Time(s)
     client 10.192.43.105 query (cache) 'doitxwx.777.liyuanxi.com/A/IN' denied: 1 Time(s)
     client 10.192.90.161 query (cache) 'v.www.90uc.com/A/IN' denied: 1 Time(s)


any idea how to suppress this?  this is centos 5.latest with bind 9.7
